In today’s installment, we’ll continue our review of Civil 3D 2018 improvements by exploring the new “Relative” Feature Line option. Generally speaking, relative feature lines can have all (or some) of their elevation points dynamically linked to a surface. Their elevations can match the surface elevations, or be assigned a vertical offset. Since they are relative, any changes made to the associated surface will also update the feature lines.
To demonstrate this new feature, I’ve created two quick videos. The first represents an abstract example, designed explore the new options and settings. In the second recording, I used relative feature lines to create a parking lot that automatically reacts when changes are made to a design surface. That being said, this is just one example. With a little experimentation and practice, relative feature lines can be used to add a dynamic component to many of your design tasks.
